Application filed April 15, 1916. Serial No. 91,453.

To all whom it may concern:

Be it known that I, SWAN G. ANDERSON, a citizen of the United States,residing at Virginia, in the county of St. Louis and State of Minnesota,have invented certain new and useful Improvements in Window-ScreenFrames, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to frames for windows and especially to such uponwhich wire screen is stretched and placed within.

window openings to act as a barrier to files, mosquitos and the like.

The principal object in view is to provide a frame of this charactercomposed wholly of metal made of a plurality of unassem bledinterlocking and telescoping parts that may be obtained in suchknockdown form and subsequently assembled by the purchaser in such amanner as to perfectly fit his individual requirements.

Another object is to provide such a frame wherein the only toolnecessary in assembling same is a ammer.

Other objects and advantages will appear in the further description ofthe device.

In the accompanying drawings forming part of this application and inwhich like reference characters represent like parts:

Figure l is a plan view of the interlocking parts of the frame.

Fig. 2 is an illustration of the method of assembling a corner of theframe.

Fig. 3 is anunder side perspective view of oneof the corners of theframe after being assembled and clenched.

Fig. 1 is a cross section taken on the line mew, Fig. 1 looking towardthe center cross bar, and

Fig. 5 is a perspective view of one of the fastening clips.

In Fig. 1 one complete side of the'frame is illustrated and havingadjacent the ends thereof, the fractional'ends ofeach cooperating side,it being understood thatthe construction of the four sides areidentical.

Each sideof the frame is composed ofa female member formed of a flatpiece of sheet metal bent longitudinally at right angles as at 1 forminga horizontal. floor ortion 2 and verticalwall portion 3. The extremeupper edge of the wall 3 is bent in wardly and downwardly forming alongitudinal flange 4 at an angle to the wall 5.

The free edge of the floor downward, forming tongue 15 extends 2 is alsoturned inward forming flange 4 though is greater than wall 3. .7

The end of the female member which is designed to receive one end of themale member forming the adjacent side of the frame is provided with anopening 6 across the floor thereof, formed by cutting three sides of thedepending tongue 7 therefrom and spaced a distance from the end, and theflange 5 terminates a distance from the extreme end just equal to thewidth of the floor of the male member.

The male member which snugly telescopes within the female member andcompletes one side of the frame, is formed in cross section identicalwith the female 'member, except being just sufficiently smaller toproperly fit therein and that the upper flange 8 thereof may notnecessarily be as extensive but preferably at least sufii a flange 5similar to the that of the flange lto the cient to form a smoothiron-cutting edge to the wall, 9 of such mem- The flange 10 upon thefloor 11 of the male member terminates a distance from the free end ofthe member just equal to the width of the cooperating end of theadjacent side ofthe frame and the extreme end 12 of the wall 9 extendsconsiderably beyond the end whose angle to the base 2 of the floor 11and is bent at right angles inwardly to fit in under the flange 4: ofthe cooperating end of the adjacent side of the frame.

' The extreme outer end of the floor 11 0f the male member is cut awaysomewhat as at 13, out again as at 1 1 and lnward a distance.

from the end just equal to the len h of the opening 6 in the dependingcurved tongue 15 which snugly fits within theopening 6 and upon thecorrespondingly shaped tongue 7 when the corner of the frame ismadecomplete by the assembling of the cooperating members.

-llt-is evident that from thefact that the below aplane with the lowerface of the bottom t being engaged therewith to admit of the end 12being surmounted by the flange 41 of the female member. I Then as thevertical walls of the two members are thus enteredgthe tongue'15 of theentering member may be snapped into to be tipped up somewhat 11 the malemem- 7' hll place within the opening 6 in the receiving member bybringing the two members into alinement.

The attitude of the engaging members for such assembling is clearlydepicted in Fig.

of the drawings. After th thus engaged they four telescopic sides to therame, as described, it is evident that such be adjusted within certainlimits to flt any sized opening preparatory to the wire screen beingapplied thereto.

fter the corners of the frame are assemhen the wire screen 16 is cut ofa size to freely fit within the side walls of the frame and rest uponthe edge of the flanges 5 and 10 now completely surrounding the innerwall of the frame.

0 bind the screen to the flanges, flat metal strips 17 are placed uponthe edges thereof and forced downward within the side walls of the framemembers and held therein by transverse clips 19, any number of which, tosuit circumstances, may be employed.

One edge 18 of the strips 17 is preferably in the form of a flange bybeing slightly turned at an angle to the body portion thereof, andagainst which the end 20 of the clips 19 are designed to impinge whenthe downward into place. By of the strips is snugly against the screenunder the flanges of t 1e frame, a firmer joint resulting than if thestrips were not flanged.

The strips 17 may be composed of one or more pieces for each side of theframe as desired and may be readily cut to suit individual requirements.

In a frame of this character, large to require additional strengthening,I provide a telescopic cross bar comprising sufiiciently the male andfemale semi-tubular members 22 and 23 respectively, the ends 24 of whichare pinched tightly together and bent at right angles to the body of thebar. When in place within the frame, the ends 24 are sprung in under theflange 4c of opposite sides of the frame and the flange forced tightlythereagainst with a hammer.

While the body portion bears against the screen upon the edge of theflange 5 of the frame, the members comprising the bar may be fixedagainst longitudinal movement by being forced together with a hammer andtie screen fastened thereto by a suitable iece of wire 25, wheredesired.

Thus I have provided a form of screen frame that can be made of aplurality of relatively small and inexpensive pieces of scoping members,the innermost flange be ing for the reception of a suitable wire screen,strips for placing within and holding the screen against the flange andclips for holding the strips securely in place.

2. A screen frame of the character described comprising side members ofangular shaped pieces of thin metal having inwardly turned flangesformed upon the opposite edges thereof, the innermost flange being forthe reception of a suitable screen,
